Project Alias — Teachable, open-source parasite for smart home devices

Alias acts as a middle-man device that is designed to appropriate any voice activated device. Alias is able to communicate and manipulate the home assistant when placed on top of it. The speakers of Alias are used to interrupt the assistance with a constant low noise/sound that feeds directly into the microphone of the assistant.

I came across this small device that you can make at home. It is open-source so you can be sure no one is spying on you through your own microphone and it seems to be the solution for privacy problems with smart home devices. I expect a whole line-up of products like this coming out the next few years.
